Simultaneous prompting, a type of antecedent prompt and test procedure, was used to teach the chained task of making juice from a frozen concentrate using a pictorial recipe to four elementary-aged students with moderate intellectual disabilities. Using a multiple probe design, all students acquired the task and maintained the behavior with at least 85% accuracy up to 60 days after training was terminated. In addition, students generalized the skill across settings and materials. The students' ability to expressively identify the words shown on the recipe cards was tested prior to and after training. Although not directly trained, three of the four students increased their ability to read the words. 相似文献

The behavioral research on teaching individuals who have profound multiple handicaps is reviewed. The primary focus is on determining the degree to which behavioral research has demonstrated the teaching of meaningful skills to this population. Results of the review indicate that investigations have demonstrated, albeit inconsistently, that behavior change has resulted from contingency management interventions with persons who have profound multiple handicaps. However, there is little evidence that such interventions have resulted in meaningful behavior change according to currently accepted criteria for beneficially affecting the quality of life of persons with serious handicaps. Potential explanations for the lack of such evidence are offered, including the relative lack of research attention given to this issue, the possible ineffectiveness of the components of the technology applied, and possible ineffective application of the potentially effective technology. Suggestions for future research are discussed in terms of developing more effective educational and habilitative services for persons with profound multiple handicaps. In particular, we suggest research on a wider variety of behavioral teaching procedures, providing more comprehensive evaluations of the applications of procedures and developing treatment programs that do not focus solely on traditional skill acquisition. 相似文献

Behavioral momentum was examined in 2 individuals with severe mental retardation via within-subject manipulations of obtained reinforcer rates. Subjects performed self-paced discrimination problems presented on a touch screen computer monitor. Two different problems, Tasks A and B, alternated in blocks of 15 trials on a multiple schedule. Reinforcers were snack foods. The reinforcement schedule for Task A was continuous (fixed-ratio 1) and the schedule for Task B was continuous in some conditions and variable ratio in other conditions. Behavioral momentum was assessed in test sessions by prefeeding, presenting response-independent food, and making available alternatives to the tasks. When the obtained reinforcer rate for Task A was at least twice that for Task B, resistance to change was greater for Task A. When both reinforcer rates and response rates were a pproximately equal for the two tasks, resistance to change was approximately equal. These results are consistent with behavioral momentum effects. They extend previous findings with humans by examining momentum in self-initiated discrete-trial discrimination tasks with ratio schedules, and by isolating relative reinforcer rates as a controlling variable via within-subject manipulations. 相似文献

Contingent physical guidance was used to treat chronic aerophagia. This consisted of guiding the participant's hand over her mouth following each attempt to engage in aerophagia. A wristwatch was then correlated with the contingent physical guidance procedure. Responding remained low in the presence of the wristwatch, even after contingent physical guidance was withdrawn. 相似文献

A number of hypotheses have emerged regarding the etiology of physical aggression in persons with mental retardation. Although a multicomponent model is appropriate, results of functional analysis-based studies have yielded promising results in identifying instigating and maintaining factors of aggression. However, the relationship between functional variables and conditions such as psychiatric diagnosis to aggressive behavior has yet to be investigated in persons with mental retardation. We conducted a study examining the prevalence of environmental or physical factors in aggressive behavior in mentally retarded persons with and without psychiatric disturbance. One hundred and thirty-five individuals with mental retardation who exhibited physical aggression were assessed with the Questions About Behavior Function Scale (QABF) to identify environmental or physical contribution to aggressive behavior. One or more behavioral functions were identified for 75% of the participants. Additionally, of 66 of the participants scoring above the clinical cutoff on an assessment for dual diagnosis, 75% met criteria for an environmental or physical function for aggression. No significant differences in number of participants with an identifiable function of aggression were found between the no dual diagnosis and dual diagnosis groups. Our findings underscore the importance of identifying functions underlying aggressive behavior in persons with mental retardation, and the need to consider functional variables regardless of psychiatric condition in treatment planning efforts for such individuals. 相似文献

Pre-Therapy is a theory conceptualizing about psychological contact practiced with low-functioning persons. This category includes schizophrenic people, retarded people, and geriatric clients who are too isolated and withdrawn for regular psychotherapy. The techniques, known as Contact Reflections, are Situational, Facial, Word-for-Word, Bodily, and Reiterative Reflections. The therapist expresses a foundational belief in implicit selfhood as presented in episodes of lucidity. There is compassion for the effort at self-expression even at regressed levels. The therapist's reception of symptomatic expression conveys empathy. The case history illustrates the application of Contact Reflections with a catatonic client without the use of neuroleptics. This gives a clearer example of the psychological effects of Pre-Therapy. 相似文献

Martha Nussbaum has sought to establish the significance of disability for liberal theories of justice. She proposes that human dignity can serve as the basis of an entitlement to a set of capabilities that all human beings either possess or have the potential to develop. This article considers whether the concept of human dignity will serve as the justification for basic human capabilities in accounting for the demands of justice for people with profound learning difficulties and disabilities. It examines the relationship between dignity and capabilities, suggesting that Nussbaum fails to distinguish between several conceptions of human dignity, whilst also identifying one of these conceptions as coming close to meeting several of her demands. It is difficult enough, however, to show how dignity is related to just one of our basic entitlements, and even that requires more than the resources available in Nussbaum's approach. 相似文献

Typically developing children have been shown to imitate the specific means used by an adult to achieve an object‐directed outcome, even if a more efficient method is available. It has been argued that this behaviour can be attributed to social and communicative motivations. The purpose of this study was to investigate whether children with autism spectrum disorders (ASD), relative to children with Down syndrome (DS), show a reduced tendency to copy the exact means used by an adult to produce a novel outcome. To achieve this a sample of 34 children (22 with ASD and 12 with DS) were given a test of object‐directed imitation. Contrary to expectation, children in both groups imitated the specific method of the model to the same high extent. This finding is in line with suggestions that object‐directed imitation is relatively spared in children with autism but is surprising given arguments linking such imitation to socially based motivations. Nevertheless, children's ability to successfully copy the model was associated with their communicative ability, providing some support for the link between imitation and communication. 相似文献

We examined choice and preference in four adults with profound mental retardation within the context of a community-based and center-based location. Prior to the preference analysis, an independent selecting response was empirically assessed and validated for each adult. Results of the preference analysis showed that in the community site there was a higher cumulative frequency of choice-making responses towards beverages for all participants, and an indication of beverage preference for two of the four participants. Conversely, in the center-based setting, there were fewer responses made towards the beverages, and no indication of preference for any of the four adults. These results remained consistent during maintenance checks at 2, 4, 6, and 8 weeks post-intervention. 相似文献
